It’s not actually much cheaper at all. If you want to get a new or refurbished model and value graphics performance, you’ll need to go with the Vega 20 to even approach the Navi graphics in the base $2400 16” model. Since Vega existed on top of Polaris for the 2019 15”, you often see them going for MORE than the base 16”. The used market is better, but not by much.
Point being, the idea that the old machines are some garbage relics now that can be had for chump change (or even a reasonably lowered price) is complete nonsense.
Um, obviously, the maxed-out old one will be more expensive than the cheapest new one. In other news, the sun is hot.
